Wireless vs 100 feet cat 6 cable

good quality CAT6 cable would bebest in almost all cases, make sure all parts used are rated CAT6 to get the full benefit.

In theory it goes CAT6>Wireless N>CAT5>Wireless G but there can be other impacting factors

thank you for your response Vibe -- Is your answer the same if I get CAT 5e and part of the cable is outside

Sorry for the delay, holiday

Cat5 and cat5e have very few differences, these days parts labled as cat5 are normaly actualy cat5e standards but have not gone through certification process.

Also something to consider is link speed. Many of the wireless N routers will include gig ethernet, assuming your TV supports it that is MUCH faster than the wireless. Either way wired in my experience usually works better than wireless.
